MARCOR OSH PROGRAM MANUAL24. Parenteral. Piercing of the mucous membranes or skinbarrier by a needle stick, human bite, cut, or abrasion.25. Potential Energy. A function of a height of an objectabove some datum plane. This datum plane is usually consideredto be where that object would come to rest if the restraintholding the object were released. For example, where the upperdie in a punch press is positioned if the restraining deviceholding the upper die in place was to be removed, the potentialenergy of the upper die would be converted into kinetic energyresulting in the upper die being propelled downward, coming torest on the lower die. This motion can cause a crushing,cutting, lacerating, amputating or fracture injury to anemployee's arm, hand or some other part of the body, whichoccupies the space between the dies.26. Potentially infectious materials include the following:a. The following human body fluids: blood, semen, vaginalsecretions, cerebrospinal fluid, synovial fluid, pleural fluid,pericardial fluid, peritoneal fluid, amniotic fluid, saliva indental procedures, any body fluid visibly contaminated withblood, and all body fluids in situations where it is difficultor impossible to differentiate between body fluids.b. Any unfixed tissue or organ (other than intact skin)from a human (living or dead).c. HIV-containing cell or tissue cultures, organ culturesand HIV-, HBV-, or HCV-containing culture medium or othersolutions, and blood, organs, or other tissues from experimentalanimals infected with HIV, HBV, or HCV.27. Residual Energy. The presence of springs; under tension orcompression or by the presence of liquids or gases underpressure (either above or below atmospheric pressure).28. Servicing or Maintenance. Work center activities such asconstructing, installing, setting up, adjusting, inspecting,modifying, and maintaining and/or servicing machines orequipment. Activities include lubrication, cleaning, orclearing machines or equipment and making adjustments or toolB-5
